What: /sys/bus/pci/drivers/.../bind Date: December 2003 Contact: linux-pci@vger.kernel.org Description: Writing a device location to this file will cause the driver to attempt to bind to the device found at this location. This is useful for overriding default bindings. The format for the location is: DDDD:BB:DD.F. That is Domain:Bus:Device.Function and is the same as found in /sys/bus/pci/devices/. For example: # echo 0000:00:19.0 > /sys/bus/pci/drivers/foo/bind (Note: kernels before 2.6.28 may require echo -n). What: /sys/bus/pci/drivers/.../unbind Date: December 2003 Contact: linux-pci@vger.kernel.org Description: Writing a device location to this file will cause the driver to attempt to unbind from the device found at this location. This may be useful when overriding default bindings. The format for the location is: DDDD:BB:DD.F. That is Domain:Bus:Device.Function and is the same as found in /sys/bus/pci/devices/. For example: # echo 0000:00:19.0 > /sys/bus/pci/drivers/foo/unbind (Note: kernels before 2.6.28 may require echo -n). What: /sys/bus/pci/drivers/.../new_id Date: December 2003 Contact: linux-pci@vger.kernel.org Description: Writing a device ID to this file will attempt to dynamically add a new device ID to a PCI device driver. This may allow the driver to support more hardware than was included in the driver's static device ID support table at compile time. The format for the device ID is: VVVV DDDD SVVV SDDD CCCC MMMM PPPP. That is Vendor ID, Device ID, Subsystem Vendor ID, Subsystem Device ID, Class, Class Mask, and Private Driver Data. The Vendor ID and Device ID fields are required, the rest are optional. Upon successfully adding an ID, the driver will probe for the device and attempt to bind to it. For example: # echo "8086 10f5" > /sys/bus/pci/drivers/foo/new_id What: /sys/bus/pci/drivers/.../remove_id Date: February 2009 Contact: Chris Wright Description: Writing a device ID to this file will remove an ID that was dynamically added via the new_id sysfs entry. The format for the device ID is: VVVV DDDD SVVV SDDD CCCC MMMM. That is Vendor ID, Device ID, Subsystem Vendor ID, Subsystem Device ID, Class, and Class Mask. The Vendor ID and Device ID fields are required, the rest are optional. After successfully removing an ID, the driver will no longer support the device. This is useful to ensure auto probing won't match the driver to the device. For example: # echo "8086 10f5" > /sys/bus/pci/drivers/foo/remove_id What: /sys/bus/pci/devices/.../vpd Date: February 2008 Contact: Ben Hutchings Description: A file named vpd in a device directory will be a binary file containing the Vital Product Data for the device. It should follow the VPD format defined in PCI Specification 2.1 or 2.2, but users should consider that some devices may have malformatted data. If the underlying VPD has a writable section then the corresponding section of this file will be writable.
